SLAG STEAM-GENERATOR.

SPECIFICATION forming part of Letters E'atent No. 711,290, dated October 14, 1902.

Application filed March 13, 1902. Serial No. 97,988. (No model.)

To (bl/1 whom, (It may concern:

Be it known that I, LUoIUs DAY COPELAND, a citizen of the United States, and a resident of Los Angeles, in the county ofTios Angeles 5 and State of California, have invented a new and Improved Slag Steam-Generator,of which the following is a full, clear, and exact description.

The invention relates to steam-generators [O in which molten or hot slag is brought in contact with water.

The object of the invention is to provide a new and improved slag steam-generator which is simple and durable in construction I5 and arranged to permit proper control of the operating parts by the workmen, to prevent escape of steam when recharging with molten slag, and to insure complete utilization of the units of heat in the molten or hot slag for convertingthe Water into steam.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both views Figure l is a sectional side elevation of the improvement, and Fig. 2 is an enlarged transverse section of part of the same on the line 2 2 of Fig. 1.

From the upper end of the generator-casing A, containing the water to be converted into steam, leads the steampipe C for carrying off the generated steam to other machinery. On the top of the generator-casing A is arranged a seat D, into which opens centrally the charging device E, preferably in the form of a gate-valve, adapted to support a funnel F, into which the molten or hot slag is poured at the time of recharging the generator, as hereinafter more fully described.

5 The seat D is adapted to be engaged by the open upper end G of the slag-receiving receptacle G,preferably cone orbell shaped,and constituting a valve for preventing the entrance of steam thereto while being charged, as here inafter more fully described. The receptacle G is engaged by a ring H, having limited sliding movement between sets of lugs G and G as plainly indicated in the drawings. The ring H is provided with trunnions 1-1, journaled in suitable hearings in the generatorcasing A, one of the trunnions extending to the outside of the casing and carrying at its outer end a handle H? under the control of the operator for turning the trunnions, so as to tilt the ring 11 and with it the receivingreceptacle G to discharge the contents thereof into the casing, as hereinafter more fully described, or for turning the receptacle back again into a filling position, as indicated in Figs. 1 and 2. p

The receiving-receptacle G is adapted to be lifted to its seat by an arm I, adapted to 011- gage a projection G on the bottom or closed end of the said receptacle G. The arm I is secured on a shaft 1, journaled in suitable 7c bearings held on the generator-easing A, and on one outer end of the said shaft is secured a handle 1 under the control of the operator for turnihg the shaft I to swing the arm I into engagement with the projection G to lift the receiving-receptacle G and move its open end G into engagement With the seat D. It. is understood that the spaced sets of lugs G G permit such movement of the receptacle on the ring H.

Now by the arrangement described the receivingreceptacle G is firmly seated on the seat D, so that when the gate-valve of the charging device is opened and molten or hot slag is poured into the funnel F then this slag passes into the receptacle Gwithout danger of steam contained in the casing A escaping through the charging device.

In order to insure an exceedingly fine contact between the end G and the seat D, I prefer to revolve the receiving-receptacle G at the time the latter is moved to its seat by the operator manipulating the handle 1 For this purpose the end G is provided with a gear-wheel G adapted to move in mesh with 5 pinions J' at the time the receiving-receptacle G is lifted to its seat. The pinions J are secured on the lower ends of shafts J, journaled in suitable bearings carried by the casing A, and on the outer ends of the said I00 shafts J are secured hand-wheels J under the control of the operator for turning the said shafts J and pinions J around for re- I ator and discharged therefrom while the wavolving the receiving-receptacle Gby the pinions turning the gear-wheel Now in case any molten slag becomes lodged between the open end G and the seat D it is evident that when the receiving-receptacle is rotated at the time it moves to its seat then such particles are ground by the revolving receptacle, and the latter finally makes firm contact with its seat to prevent the escape of steam. After the receiving-receptacle G is filled with molten or hot slag then the gate-valve is closed, and in order to equalize the pressure in the receiving-receptacle and the inside of the generator A, I provide an equalizing-pipe K, leading from the casing A into the lower portion of the charging device, so as to equalize the pressure on the receiving-receptacle to permit of conveniently lowering the latter on moving the handle I upward. Usually the weight of the charged receptacle G is sufficient to move the latter downward into, the position shown in Fig. 2 as soon as the pressure is equalized.

The pipe K is provided with a suitable valve K under the control of the operator for opening or closing the pipe.

Below the receiving-receptacle G is arranged a cross-bar L, secured to the genera tor-casing A, its object being to break the contents of the receiving-receptacle to avoid an explosion, which would result if dropped into the water unbroken at the time the re- .ceptacle is tilted by the operator moving the arrangement the molten or hot slag in the receptacle G is divided on leaving the receptacle, and falling in a divided state into the casing A causes a quick generation of steam.

The top of the generator-casing A is provided with a suitable safety-valve N, (see Fig. 1,) and the lower end of the said casing Ais preferably connected by a gate-valve O with a vessel P, in which the slag and the water not converted into steam can accumulate. The water and accumulated slag are periodically removed from this vessel P at the time the gate-valve O is in a closed position by means of a hinged bottom B. This bottom R constitutes a valve for maintaining pressure while slag is being discharged from the generator into the said vessel. The wator-supply pipe Q is preferably located near the top of the vessel P to fill the latter and the generator-casing with water at the time the valve 0 is open.

The apparatus herein described is an improvement in the apparatus disclosed in my application, Serial No. 78,321, filed October 11, 1901. In the latter no provision is made for feeding slag into the generator-casing and discharging it therefrom without permitting the steam to escape from the generator, while the apparatus disclosed herein is constructed and adapted to generate a continuous supply of steam under pressure, its construction being such that slag may be fed into the generter therein is under pressure.
